Claims
exact text as granted — not AI-modified1 .- 21 . (canceled)
22 . A composition used in the method of claim 42 , the composition comprising:
a first reagent capable of generating a first chemical species in at least one of the composition, a solution containing the composition, and a film formed from the composition; and a precursor that is capable of generating a second chemical species through an interaction with the first chemical species.
23 . The composition of claim 22 , wherein the first reagent is capable of generating the first chemical species through a first exposure of at least one of the composition, the solution, and the film to at least one of a first electromagnetic ray having a first wavelength and a first particle ray.
24 . The composition of claim 22 , wherein the precursor is capable of generating the second chemical species through a second exposure of at least one of the composition, the solution, and the film to at least one of a second electromagnetic ray having a second wavelength and a second particle ray.
25 . The composition of claim 22 , wherein:
the first chemical species is capable of generating a first product; and the first product is capable of acting as a photosensitizer.
26 . The composition of claim 22 , wherein:
the first chemical species is capable of generating a first product; and the precursor is capable of generating the second chemical species through a third exposure of at least one of the composition, the solution, and the film by at least one of a third electromagnetic ray having a third wavelength and a third particle ray.
27 . The composition of claim 23 , wherein the first electromagnetic ray and the first particle ray is an extreme ultraviolet light.
28 . The composition of claim 26 , wherein:
the third exposure is carried out using the third electromagnetic ray; and the third wavelength is longer than 250 nm.
29 . The composition of claim 24 , wherein the second wavelength is longer than the third wavelength.
30 .- 41 . (canceled)
42 . A method of manufacturing a device, the method comprising: placing a composition on a member such that a film including the composition is disposed on the member;
first exposing the film to at least one of an electron beam and a first light, the wavelength of which is shorter than 50 nm; second exposing the film to a second light, the wavelength of which is different than the first wavelength; and third exposing the film to at least one of a third electromagnetic ray having a third wavelength and a third particle ray, wherein
the second wavelength is longer than the third wavelength;
the third wavelength is longer than the first wavelength; and
the composition includes a first reagent able to generate a first chemical species and a precursor that generates a second chemical species.
43 .- 44 . (canceled)
45 . The method of claim 42 , wherein a first period in which the first exposure is carried out does not overlap temporally a second period in which the second exposing exposure is carried out.
46 . The method of claim 42 , wherein:
the first chemical species is generated by the first exposure; and the first chemical species is a ketyl radical.
47 . The method of claim 42 , wherein:
a first product is generated from the first chemical species; and the first product is a ketone compound.
48 . (canceled)
49 . The method of claim 42 , wherein the precursor generates a second chemical species by the third exposure.
50 . The method of claim 42 , wherein the first product enhances the generation of the second chemical species from the precursor by absorbing the third electromagnetic ray.
51 . The method of claim 42 ,
wherein: the first chemical species has a lifetime in the film; and the first chemical species is excited within the lifetime of the first chemical species by the second exposure.
52 . The method of claim 51 , wherein:
the first chemical species is generated by the first exposure; and the exciting of the first chemical species is carried out by the second exposure.
53 . The method of claim 42 , wherein the second wavelength is longer than 400 nm.
54 . The method of claim 53 , wherein the third wavelength is longer than 250 nm.
55 . The method of claim 42 , wherein the first reagent is an alcohol compound or an alcohol derivative with a hydroxyl group protected, as an acid generation enhancer.
56 . The composition of claim 22 , wherein the first reagent is an alcohol compound or an alcohol derivative with a hydroxyl group protected, as an acid generation enhancer.
57 . The method of claim 42 , wherein the first reagent is an alcohol derivative with a protected hydroxyl group.
58 . The composition of claim 22 , wherein the first reagent is an alcohol derivative with a protected hydroxyl group.
59 . The composition of claim 23 , wherein the first particle ray is an electron beam.Cited by (0)
